Optical Isolation with Microring Modulators
Nathan Dostart, Hayk Gevorgyan, Deniz Onural +1
Optical isolators, while commonplace in bulk- and fiber-optic systems, remain a key missing component in integrated photonic systems. Isolation using magneto-optic effects has been…
Multiplexing Guided Optical and Acoustic Waves for Efficient Acousto-Optic Devices
Nathan Dostart, Miloš Popović
Acousto-optic devices utilize the overlap of acoustic and optical fields to facilitate photon-phonon interactions. For tightly confined optical and acoustic fields, such as the sub…
